Sympathetic nervous system assessment was done using cold pressor test
(CPT), handgrip test (HGT), and blood pressure (BP) response to standing.
Blood pressure response to cold pressor test
in siblings of hypertensives.
The researchers measured heart rate variability while the volunteers engaged in controlled breathing (12 breaths/min for 1 minute), rested in a tilted, 70-degree head-up position (4 minutes), and engaged in a cold pressor test
(CPT) during which a lower arm was immersed in ice-cold water (2 minutes): "Controlled breathing stimulates parasympathetic nerve activity, whereas tilting and CPT stimulate sympathetic nerve activity.
Heart rate (HR) and BP were measured at rest, after 10 min seated, and after the cold pressor test
, 20 m shuttle-run test, and handgrip test.
After baseline blood sampling, a cold pressor test
(CPT)  was conducted to assess pain sensitivity prior to exercise.
The slope of the PPG signal raising front has been analysed during the cold pressor test
in order to monitor cardiovascular and nervous system reactivity .
Cold Pressor Test
(CPT): The right hand of the subject was immersed up to the wrist in cold water at a temperature of 4[degrees]C for 1 minute.
The cold pressor test
is a cardiovascular test performed by immersing the hand into an ice water bath until pain is unbearable and measuring changes in cardiovascular pharmacodynamic parameters.
2010) Heat stress attenuates the increase in arterial blood pressure during the cold pressor test
They reported pain tolerance and pain rating in cold pressor test
in three different musical conditions served as the outcome measures.
The study was employed using the cold pressor test
(placing one hand up to the wrist in ice water for a brief period), which is an established means of noninvasively activating the sympathetic nervous system (cf.
Heart rate variability was measured at baseline and after 12 weeks using 24-hour time and frequency domain measures and during a 5-minute mental arithmetic stress test and a 5-minute forehead cold pressor test
